Entries for October 2009

Released into the wild, the DevCentral team is back from our week of being sequestered in a conference room discussing the meaning of life, the universe and everything. Well…everything as it pertains to DC, at least. We even rolled successfully to save against being mauled by zombies or turned into newts (hey…it's almost Halloween, gimme a break…). As such there is plenty of content to pour through this week, including a very cool talk with a newbie to the F5 family. As always I'll give you my p...
What could you do with your code in 20 Lines or Less? That's the question I ask (almost) every week for the devcentral community, and every week I go looking to find cool new examples that show just how flexible and powerful iRules can be without getting in over your head.Well we made it to 30 editions of the 20LoL.  Soon we’ll break 100 iRule examples that are under 21 lines of code each.  Pretty neat stuff, if you ask me.  This week is the hoolio show, it seems.  The guy is just a monster in t...
After reviewing the flood of entries (thank you ALL!) in 2009 contest, we’re ready for what I’ve been most excited about: your chance to select the winner of this year’s iRule. Do You? contest. If you want to skip the extra blabbering from me, you click here and vote! Otherwise, here are some more details about the contest. As you’ve probably noticed, we’re running a bit behind our original schedule. It’s directly due to the many entries and due diligence from our judging team to spend the n...
Cloud computing is, at its core, about using resources in the most operational and financially efficient manner possible. It’s about spreading resources around and sharing them to achieve greater scalability with fewer investments in hardware and software. But what if you aren’t moving to cloud? Or virtualization? Or perhaps you are, but the benefits won’t be really seen until you actually get enough resources shared across your organization. Isn’t there any other way to better utilize the resou...
Social Networks are now part of our society for better or worse.  It has allowed us to both connect with current friends and find pals from the past; it offers businesses another outlet for marketing and sales; it allows us to collaborate, discuss and converse on any topic imaginable.  And due to it’s popularity, it also gives thieves and other criminal types an inroad to deliver malware, steal identities, spam, stalk, and many other nasty things to expose personal and corporate information.  Si...
Carrying over the provisioning and capacity planning techniques used in a traditional data center to cloud computing negates the full power of the Force cloud computing. One of the benefits of cloud computing is supposed to be efficiency, particularly in the utilization of compute resources. Over-provisioning of compute resources has long been one way in which IT combats the need for scalability and availability of applications but this often leaves a large percentage of compute resources unus...
Vertical scalability used to require optimizations inside the application, at the code level. Cloud computing changes the nature of vertical scalability and, one hopes, will lead to a new model of scalability based on the capabilities of Infrastructure 2.0 and increasingly granular resource management capabilities. RightScale recently offered up its own analysis of Amazon Usage Estimates and while the details they provide on Amazon usage from their vantage point is very interesting I found one...
There is a common myth that the reason legacy code continues to run in businesses around the world is that no one understands it; that IT and businesses are afraid to replace it because they don’t know what it does. Once again, living in the mainframe capital of the world (the insurance industry heavy midwest), I get to talk to IT folks who deal with legacy software and hardware all the time. Do not doubt that they know exactly what that legacy software does and how it works, and perhaps frigh...
Paul Miller, who pens Cloud of Data, had an interesting perspective during a chat this week on what effect infrastructure upgrade cycles might have on cloud computing adoption. Paul postulated that as these servers fail and organizations have to make the decision to replace or not replace them that cloud computing becomes a more viable option. That seems a reasonable assumption, especially if the primary reason organizations are evaluating cloud computing is driven by a desire to reduce costs. B...
